Although this book contains a number of passages where truth is set forth with great eloquence, alas it also maintains a number of very serious errors and perversions of the the truth. An example of one deadly error is the chapter entitled 'The Investigative Judgement' in which a fundamental error with regards to the saving work of the Lord Jesus Christ is set forth. This flies in the face of Scriptural doctrine which teaches that a person is justified by faith in Jesus Christ — Romans 5:1 etc. A person is justified at conversion, not some fictitious date (1844!).
So my conclusion is BEWARE, there is a lot of sugar in this book to help you swallow the poison. Not recommended, especially not a true guide to how to be right with God. Beware the writings of Ellen G White, the Bible as well as history have exploded her distinctive ideas on Scripture doctrine.

The first reviewer to rate this book gave it a glowing 5-star rating, indicating that it is the second greatest book in the world and has EQUAL LIGHT as the Bible. I'm sorry, I must disagree with this assessment. It's misleading. I'm not saying this book has no value and as much as I dislike using a low rating to offset someone else's unreasonably high, I think a rating somewhere in the middle is more reasonable. Judge for yourself.

What is the FIRST Greatest Book in the world?
You know. THE BIBLE
But very few know that "THE GREAT CONTROVERSY BETWEEN CHRIST AND SATAN is the SECOND GREATEST BOOK in the world. THIS IS NO ORDINARY BOOK. It is a reflection of the BIBLE in more detail. It is not a lesser light, but the same light as the BIBLE. This book was inspired by God Himself. It contains more messages to God's church. The Bible says these messages were given to holy men [and women] as they were moved the the Holy Spirit. 2Peter1/21
It reveals Satans activities and plans throughout the history of the world. Satan hates this book. You will love it.
